Instructional Ideas
- Assign for kids to complete at home, and have them write up a short lab report to review their findings
- Put kids into groups or pairs to complete the experiment
Classroom Considerations
- One misspelling may impede understanding (retaining walks instead of retaining walls)
- Experiment may require a lot of modeling for younger learners
Pros
- Prompts kids to use their observation and deductive skills in order to complete the experiment
Cons
- Doesn't provide opportunities for kids to make their own hypotheses; consider coming up with a class hypothesis before beginning the activity
